Hibiscus rosa-sinensis plant named &#39;enlightenment&#39;

ABSTRACT

A new and distinct cultivar of  Hibiscus  plant named ‘ENLIGHTENMENT’, characterized by a large, ruffled, multicolored flower with a pink center, an orange halo and yellow edges, with white flecks throughout the center. ‘ENLIGHTENMENT’ is a free flowering plant with an upright, compact habit, and glossy, dark green foliage.

BOTANICAL CLASSIFICATION

Hibiscus rosa-sinerinsis ‘ENLIGHTENMENT’.

VARIETAL DENOMINATION

The new plant has the varietal denomination ‘ENLIGHTENMENT’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hibiscus, botanically known as Hibiscus rosa-sinensis and hereinafter referred to by the cultivar name ‘ENLIGHTENMENT’.

The genus Hibiscus comprises about 250 species of herbs, shrubs and trees in warm temperate and tropical regions; with leaves usually simple, mostly palmately veined, lobed or parted; flowers are mostly solitary in the leaf axils but sometimes in racemes, corymbs or panicles. Hibiscus is included in the family Malvaceae, which comprises about 95 genera of herbs, shrubs and trees originating in tropical and temperate regions. Hibiscus rosa-sinensis is a glabrate shrub, seldom over 8 feet tall in cultivation, but treelike to 15 feet or more in tropical regions. Leaves grow to 6-inches in length, and are ovate, usually serrate, mostly glossy green. Flowers are solitary in upper leaf axils.

The new Hibiscus is a product of a planned breeding program conducted by the Inventor in Webster, Tex. The objective of the program was to create new Hibiscus selections with improved bloom quality, color and floriferousness. A further objective was to produce plants that can be commercially produced on their own root systems, with improved plant habit, with regard to vigor and postproduction longevity.

The new variety was discovered in a controlled breeding program of Hibiscus rosa-sinensis and differs from its parents and other known cultivars of Hibiscus rosa-sinensis by the following characteristics in combination:

1. Upright, compact symmetrical plant habit that is suitable for container production;

2. Healthy dark green foliage;

3. Vigorous growth habit;

4. Large ruffled multicolored flower with a pink center, an orange halo and yellow edges, with white flecks throughout the center; and

5. Free flowering.

SUMMARY OF THE INVENTION

The cultivar ‘ENLIGHTENMENT’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, nutrition and water status without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘ENLIGHTENMENT’. These characteristics in combination distinguish ‘ENLIGHTENMENT’ as a new and distinct cultivar:

-   -   1. Upright, compact symmetrical plant habit that is suitable for         container production     -   2. Healthy dark green foliage.     -   3. Vigorous growth habit.     -   4. Large ruffled multicolored flower with a pink center, an         orange halo and yellow edges, with white flecks throughout the         center.     -   5. Free flowering.

Asexual reproduction of the new variety by stem cuttings, performed in Webster, Tex. and Houston, Tex., have confirmed that the distinctive characteristics of the new variety are stable and transmitted to succeeding generations, and the new variety reproduces true to type.

COMPARISON WITH PARENTS AND OTHER CULTIVARS

‘ENLIGHTENMENT’ is distinguished from its female parent ‘Georgia's Pearl’ (not patented) by its flower color, the flower of ‘ENLIGHTENMENT’ having more yellow and less orange than that of ‘Georgia's Pearl’. ‘ENLIGHTENMENT’ is distinguished from its male parent ‘Jason Blue’ (not patented) in the flower color, ‘Jason Blue’ having a silvery blue eye not found in ‘ENLIGHTENMENT’.

The closest commercial cultivar to ‘ENLIGHTENMENT’ known to the inventor is ‘Sun Shower’ (not patented). However, in side-by-side comparisons conducted in Webster, Tex., plants of ‘ENLIGHTENMENT’ differ from plants of ‘Sun Shower’ in the following characteristics:

-   -   1. Flowers of the new hibiscus have a different color pattern         than flowers on the cultivar Sun Shower;     -   2. Plants of the new Hibiscus are easier to clone via rooting         than plants of the cultivar Sun Shower; and     -   3. Plants of the new Hibiscus possess an improved growth habit         over that of the cultivar ‘Sun Shower’, which is usually         sprawling and difficult to maintain in production and as a         landscape plant.

‘Enlightenment’ also has a sibling, namely the Hibiscus rosa-sinensis ‘Hollywood’ (U.S. Plant application Ser. No. 11/213,646). Although these plants are closely related, they both have distinctive flower coloration. Specifically, the two flowers differ in the following ways:

1. ‘Enlightenment’ has a pink center, ‘Hollywood’ does not;

2. The dominant colors on ‘Enlightenment's’ flower are pink, orange and yellow, and for ‘Hollywood’ it is red, orange and yellow; and

3. ‘Enlightenment’ has white flecks throughout the center while ‘Hollywood’ does not.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying illustrations show a specimen of the new cultivar in a photographic illustration as true to color as is reasonably possible to make in an illustration of this character. Color values in the illustrations may differ slightly from the color values cited in the detailed botanical description, which accurately describes the actual colors of the new Hibiscus.

DETAILED DESCRIPTION OF THE INVENTION

‘ENLIGHTENMENT’ has not been observed under all possible environmental, cultural and light conditions. The following observations and descriptions are of plants grown in Fulshear, Tex., in April 2005, under polypropylene shadecloth providing a 30 percent light reduction, and under conditions which closely approximate commercial production. Plants described were approximately one year old.
